If you're not familiar, Google's Accelerated Mobile Pages project aims to make the mobile web faster and less data-heavy. Websites that choose to support it offer AMP versions of their pages, which are then loaded instead of the full site. Google mobile search and the mobile Google+ site already load AMP pages when available, and now the latter's native Android app is joining in.

It's been a rough year for Samsung, but the Supreme Court just gave the company a big early Christmas present... or at the very least, they denied one to Apple. Reuters reports that the highest court decided unanimously (8-0) that the $399 million in damages sought by Apple in the years-old iPhone design patent case was too much, siding with Samsung's appeal which said that copying only certain elements of the iPhone design patent didn't entitle Apple to all profits made from an infringing phone.

Duo hasn't been the hit success that Google expected it to be, but that should only serve as motivation for engineers to make it better. The video-chatting app has just been updated to version 5.0, which not only fixes a few bugs, but also improves on the entire user experience.

More and more Live Cases are becoming available, bringing a wide variety of phone protection to suit most aesthetic preferences. In keeping with this, Google announced the En Masse line of Live Cases in collaboration with the multi-artist collaborative group EN MASSE, who specialize in large-scale, "spontaneous" drawings.

The nicest thing about having Dropbox on a phone, at least for most users, is the ability to instantly back up photos as soon as they're taken. Accessing other files stored on the cloud is sort of secondary, if only because the mobile client doesn't constantly sync files down and up, like the desktop versions of the program do. Today Dropbox is expanding its capabilities in that area with permanently-assigned offline folder access. But make sure to read the fine print, power users - there are still some important limitations to this feature.

The Phab 2 Pro is the first phone to feature Google's Tango. Tango is, to put it lightly, not really ready for anyone aside from curious tech reviewers and maybe developers looking to get into AR content. The Phab 2 Pro itself also isn't a very good phone, and frankly costs too much to justify a largely gimmicky feature. In short, this product has "commercial flop" written all over it, and I think even AR enthusiasts and Tango phones can understand that. I honestly didn't ever expect it to be commercially marketed: this is a gadget that has some novelty and development value, but essentially zero real consumer appeal at this time.

Google is known for periodically offering free goodies to Chromecast owners. Most recently, Google gave three free months of HBO Now with purchase of a Chromecast. In the Chromecast Ultra's first promotion, you can grab a free copy of the Ghostbusters remake in 4K from Google Play Movies. It may not be the best-performing movie this year, but you can't beat free.

The offer is available to anyone who has purchased and activated a Chromecast Ultra before December 31st, and you can redeem the offer until April 30. As you might expect, this is only valid in the United States and Canada.

Way back in the day, app updates in Google Play would be the whole new APK. That changed back in 2012, and Google has been working to reduce the size of updates ever since. In its most recent triumph, the Google Play team has devised a system to reduce app update sizes by an average of 65%, but it won't be used all the time.
